HERMAN L. GREVE, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE INTERNATIONALMAILING TUBE 82; WRAPPER COMPANY, OF BROOKLYN, NEW YORK.

i 1 l MAILING WRAPPER,

To all whom it may concern:

.Be it known that HERMAN L. Gnnvn, a citizen of the United States, and aresident of New York city, in the borough of Brooklyn, in the county ofKings and State of New York, has invented certain new and usefulImprovements in Mailing Wrappers, of which the following is aspecification.

My invention relates to wrappers for merchandise and especially tomailing wrappers therefor.

The object of my invention is to provide a cylindrical shaped mailingwrapper comprising an inner sheet of rather stiff heavy material and anouter sheet of comparatively thin and flexible material held together,the inner sheet being permanently pressed by suitable means into acurved form to permit the wrapper being folded manually.

Referring to the drawings which form a part of this specification,

Figure 1 is a front view of a wrapper embodying my invention, shownpartly in section.

Figure 2 is a similar View illustrating a modification in construction.

Figure 3 is an end view of the construction illustrated in Figure 1.

Figure 4 is a view of the wrapper before 30 the ends of the outer sheetare tucked within the cylinder to close the wrapper.

I prefer to make the wrapper of paper stock, the inner sheet being of athickness and stifiness too great to be properly rolled into cylindricalform by the hands only.

A, indicates the inner sheet and B the outer one.

In Figure 1, I have shown the two sheets held together over the entireadjacent contacting surfaces between sheets A and B, the gummed surfaceof sheet A being indicated by C. The two sheets are first cementedtogether in their flat condition and the gum allowed to dry or nearlydry, and in the drying process the inner sheet tends to bend in theopposite direction to that required to provide the wrapper with thethick sheet inside, and therefore it is necessary to place the sheetsbetween rollers and roll the same into the desired form, the fibres ofthe cardboard being pressed and stretched until'it retains its properform, substantially as illustrated in Figure 3.

In Figure 2 the lower ends only of the two sheets are shown cementedtogether as Application filed March 18, 1922. Serial No. 544,819.

illustrated at D. The sheet B is preferably made longer and of greaterwidth than sheet A, and its ends BB' respectively, are tucked into theopen ends of the wrapper to close the package. By reason of the heavyinner sheet being formed as illustrated, it is comparatively easy toroll it into the completed cylindrical form illustrated in Figure 4whereas without being so formed it would be very difficult to bind theinner sheet and from a practical commercial standpoint, entirelyimpractical.

By constructing a wrapper in this Way a much stronger casing is providedof a two sheet construction than heretofore, in so far as I am aware.

Having thus described my invention I claim as new:

1. A mailing wrapper comprising an inner sheet of stiff material havingnon-corrugated surfaces, and a relatively thin outer sheet of greaterarea attached thereto and adapted to inclose the inner sheet, said innersheet being molded into a. permanently curved shape to form a restrictedopening and facilitate its being formed into cylindrical shape, andthereafterbeing incapable of assuming a flattened out position byitself.

2. A mailing wrapper comprising an inner sheet of stiff material havingnon-corrugated surfaces, and a relatively thin outer sheet of greaterarea attached thereto at its lower end and adapted to inclose the innersheet, said inner sheet being molded into a permanently curved shape toform a restricted opening and to facilitate its being formed intocylindrical shape and thereafter being incapable of assuming a flattenedout position by itself.

3. A mailing wrapper comprising an inner sheet of stiff material havingnon-corrugated surfaces, and a relatively thin outer sheet of greaterarea attached thereto at its lower end only and adapted to inclose theinner sheet, said inner sheet being moulded into a permanently curvedshape to form a restricted opening and to facilitate its being formedinto cylindrlcal shape, and thereafter being incapable of assuming aflattened out position by itself.

4:. A mailing wrapper comprising an inner sheet of stiff material havingnon-scored surfaces, and a relatively thin outer sheet of greater areaattached thereto and adapted to inclose the, inner sheet, said innersheet being moulded into a permanently curved shape to form a restrictedopening and to facilitate its being formed into cylindrical shape andthereafter being incapable of assuming a flattened out position byitself.

5. A mailing Wrapper comprising a fiexible outer sheet and a smallerstiff inner sheet normally curved in form to facilitate rolling thewrapper into cylindrical shape secured to said outer sheet, thelongitudmal edges of the said inner sheet forming a restricted openingto enable quick and easy insertion of the article to be Wrapped.

6. A mailing Wrapper comprising a flexible outer sheet and a smallerstiff inner sheet normally curved in form to facilitate rolling theWrapper into cylindrical shape attached to the outer sheet at the loweredges, the longitudinal edges of the said inner sheet forming arestricted opening to enable quick and easy insertion of the article tobe Wrapped.

Signed at Brooklyn, New York, in the county of Kings and State of NewYork this 15th day of March A. D. 1922.
